I was thinking about the OP point and found it sad on a few levels really. Partly because it sucks that the situation is so bad that they feel they have to bail but also because it feels like somebody seeing a serious problem within a broad creative medium and walking away as if to avoid being somehow tainted by association rather than acting in solidarity with those who suffer most because of toxic behaviour and trying to make a positive impact. I'm not saying that's necessarily easy, I just find the dynamic of identifying a problem and then deciding to abandon the medium on that basis feels counter-productive.
Don't misconstrue this as trying to be insensitive or lacking empathy. If you're in a situation where you're feeling victimised, upset or in a broader sense the toxicity directed at others makes you anxious or upset then by all means step out and look after yourself. I've done the same in certain spheres of my life, where a hobby seems so connected mentally with feeling anxious or anger or something else negative that I can't take part. To stress, that's not what I feel like I saw from the post and if I'm wrong then I'm sorry, it just comes across in the tone of saying 'I'm one of the good ones'.
Misogyny, homophobia, racism, macho culture and other hurtful, shitty behaviours are prevalent in parts of gaming because it's pervasive in our society and that needs to be smashed. How you do contribute to that depends on your own safety and health and so on but if you're able to that means calling it out head on and combatting it. And if you feel unable to do that, then to talk about your experiences, to promote non-shitty, inclusive behaviours, to not engage in discrimination, to support inclusive, fun communities within gaming. But whatever you can or can't do, the core thing is that we need voices like that within gaming, not out of it.
I'm a football (soccer) supporter, I love the sport and fan culture. There are elements within that culture that need combatting and lots of fans actively oppose that discrimination when it rears its ugly head. That changes football culture and makes people feel less alienated and alone. Fans could just walk away and abandon football to the bigoted minority but it's too important. So's gaming- at its best, it's a wonderful, inclusive medium of creativity that's worth fighting for and not letting shitheads ruin it.
As it stands, statements like in the OP feel aloof and somehow 'above' the problems in gaming. That the best thing to do when faced with toxicity is to publicly make a show of going 'I don't like this, everybody, and I'm not going to be tainted by it' which as far as I can tell is just walking away from the problem. By all means, sell all your gaming stuff and never bother with the hobby again. But if you do care about this stuff as you so obviously do, your voice is far, far more useful and valuable staying involved than it is on the outside. To reiterate, if toxicity is damaging you, take time out temporarily or permanently, you do you. But if you can, I'd say stay, embrace the very real, very prevalent positives that exist within the wider gaming community and use your voice and experiences to help stop toxicity getting worse.
When someone is being harassed or treated horribly or being abused in-game, people like you who care and give a shit are a thousand times more useful in our hobby than on the outside writing it all off by association. What gaming is and can be is defined by those involved in it and it only gets worse if our reaction to toxic behaviour is just to put it all in the bin and walk away.
